Answer:
21
Step-by-step explanation:
So we know the ratio is 3/4:1
So if she has 28 ounces of white pain, we can do 28*3/4=21. You could also do 28/4 (find out how much 1/4 of the value is) which is 7 and then multiply that by 3. What your basically doing is your putting it into 4 equal parts and then just multiplying by 3 since that's the amount of parts you need/have.

Answer:
y = -1/3x + 5
Step-by-step explanation:
Find slope.
m = y₂ - y₁ / x₂ - x₁
Two points given.
(0,5) (3,4)
m = 4 - 5 / 3 - 0
m = -1 / 3
y = -1/3x + b
Substitute x and y by an point. Let's take (0,5)
0 - x
5 - y
5 = -1/3(0) + b
5 = 0 + b
5 - 0 = b
5 = b
So,
y = -1/3x + 5
